As much as he wanted to forget the events of the night before, they all came rushing back the moment he opened his eyes. The videos Sophie had sent played in his head. The sight of Lauren kissing someone else was the forefront of his mind, and just like the night before it brought with it a wealth of feelings, most of which Carson found confusing.</p><p>He felt a little bit of shame for having masturbated as he watched someone else finger his wife. It was so far from anything that had ever turned him on and he still couldn’t fathom why he’d experienced such an intense kind of desire, and why he was experiencing that desire once again.</p><p>Carson looked towards his phone and thought of the pictures and videos that waited in the text from Sophie. He considered grabbing it and heading for the bathroom. He told himself he shouldn’t, that doing so was unquestionably the wrong thing, and yet his body seemed to want it.</p><p>“Trouble sleeping?” Lauren asked.</p><p>Carson whipped his head around and saw Lauren smiling at him. “Yeah, I guess.”</p><p>Lauren moved closer and pressed her body against his. She was still in the bra and panties she’d worn the night before and Carson couldn’t help but think that someone else’s fingers had been inside those panties, that his wife had happily let another man play with her pussy and that she’d done it because Carson hadn’t tended to her sexual needs in recent months.</p><p>“Is there anything I can do?” Lauren asked in a voice filled with a kind of subtle naughtiness that suggested she was offering to fool around.</p><p>Carson wanted to say yes. He wanted to tend to the lust that had presented itself the moment he woke up. It felt strange to do so, though. He couldn’t very well fuck his wife while thinking about her being with another man, could he?</p><p>Before he could answer, Lauren reached between his legs and found his half-hard cock. She stroked him and unleashed a quiet, lusty moan. Carson pictured her getting fingered in the booth and his cock came alive.</p><p>“Mmmm, it looks like there is something I can do,” Lauren said. She pushed the covers back, pulled off his boxers, and straddled him before Carson could say anything.</p><p>Lauren unhooked her bra, freeing the breasts he’d spent so much of his life enjoying. Carson reached up to take them in his hands and his wife smiled as she moved her hips over his crotch. His cock pressed against her panties and every little movement produced shocks of pleasure that emanated from between his legs.</p><p>“Do you want me?” Lauren asked.</p><p>“Yes,” Carson said. He felt a certain amount of confusion about the events of the night before, but he wasn’t the slightest bit confused about his desire for his wife. His cock was hard as a rock, she looked beautiful, and he wanted to be inside her.</p><p>Lauren reached down, pulled her panties aside, and took him inside her. Carson’s hands remained on her breasts and he played with them as she moaned and began to rock back and forth on his cock.</p><p>“You’re so wet,” Carson said. Lauren moaned and he couldn’t help but wonder if she was thinking about the guy from the night before. Was she riding his cock and wishing she had someone else inside her? For some reason that thought turned Carson on. Some part of him wanted Lauren to be thinking about someone else. He knew it was insane, and yet he couldn’t stop the cascade of dirty thoughts that ran through his head as Lauren rode him.</p><p>Lauren lowered her body on top of his and they kissed as he grabbed her ass. He squeezed it like the man had done the night before. She moaned and Carson wondered if his wife was thinking about the guy at the bar. Was she wishing it was his hands on her ass? Was she dreaming of it being his cock inside her?</p><p>“You feel so good,” Carson said between kisses. “Your pussy feels so good.”</p><p>Lauren smiled and kissed his neck. She moaned in a way he was certain he hadn’t heard in a long time. It was a moan of wild abandon, of the kind of passion that they hadn’t experienced together in years. It was intoxicating and it brought Carson ever closer to his orgasm as visions of his wife kissing someone else continued to fill his head. The jealousy and anxiety of that mixed with the pleasure of having sex with her, creating a potent concoction that drove Carson to sexual heights he hadn’t reached in years.</p><p>“Lauren…I’m close,” he said.</p><p>She moaned and rode him faster. Carson closed his eyes and surrendered to his desire. He pictured the video of his wife getting fingered in the booth at the bar. He heard Sophie’s voice telling him that Lauren loved it. She loved getting fingered by another man. It all played out in his head as her soaking wet pussy milked his cock.</p><p>“Oh…fuck,” Carson said.</p><p>Lauren sat up, put her hands on his chest, and unleashed a loud, low moan. Her eyes were closed and she wore a look of pleasure on her face. Carson recognized that look. She was close to cumming.</p><p>He couldn’t hold out any longer, though. He came inside his wife. His body shook with pleasure. The orgasm was better than any he could remember in recent years. It was everything an orgasm was supposed to be.</p><p>Thankfully, Lauren came just a few moments later. She stopped riding him and threw her head back. Her screams were loud enough that Carson was thankful Sophie was in the guest house or she absolutely would have heard them.</p><p>“Wow,” Carson said when Lauren finally opened her eyes and laid on his chest.</p><p>“Yeah, I know,” she replied.</p><p>Again Carson felt a little of the shame from the night before. He’d just fucked his wife while thinking about her fooling around with someone else and he’d enjoyed it far more than expected. It didn’t seem like the sort of thing a man was supposed to enjoy, and yet he couldn’t help it. He tried not to think too hard about it. After all, he’d just had a great orgasm.</p><p>“It’s been a long time since we showered together,” Lauren said. “Usually you’re in a bit of a rush to get to work, but you got up early today, so how would you feel about a shower?”</p><p>“I’d love that,” Carson said.</p><p>Lauren kissed him and lifted her pussy from his cock. She climbed out of bed and headed towards the bathroom. He pushed away any thoughts of shame and followed her for the first post-coital shower they’d taken in years.</p><p>Carson was eating an impossibly bland salad at his desk when Sophie called. He put his AirPods in and said, “Hey Sophie. What’s up?”</p><p>Carson listened but Sophie offered no response. He heard what sounded like ice being dropped into a glass.</p><p>“Sophie? Hello?” he asked. Still there was no response.</p><p>“So, how are you feeling?” Sophie asked.</p><p>“Good, I guess,” Carson said.</p><p>“Good,” Lauren said. “And bad, I guess. I don’t know, it’s strange.”</p><p>It took Carson a few seconds to deduce that Sophie had called and muted him. She hadn’t asked him how he was feeling. She’d asked Lauren and he was listening in on their conversation. His first impulse was to hang up, but he couldn’t bring himself to do it. He had to listen.</p><p>“Let’s start with the good,” Sophie said.</p><p>“Well, Carson and I had sex this morning,” Lauren said. He could hear the glee in her voice. It made him smile. He wasn’t the only one that had enjoyed the sex.</p><p>“Good sex?” Sophie asked.</p><p>“Great sex,” Lauren replied. “The best sex we’ve had in a long time.”</p><p>There was a brief pause before Sophie asked, “So, what’s the bad part?”</p><p>“The bad part? Sophie, I cheated on my husband last night. I know I didn’t actually have sex with someone, but I made out with someone and I had his fingers inside me. I mean, that’s not good,” Lauren explained.</p><p>Carson put his fork down as he felt those same sensations of desire stirring between his legs. Again he considered ending the call and again he failed to do so.</p><p>“Is it bad, though?” Sophie asked. “I know we haven’t seen each other much in the past five years, but I know you, Lauren, and I saw the unhappiness in your eyes last night. I saw how the slow death of your sex life was affecting you. I think we both know your marriage isn’t going to last long if you can’t find a way to fix it. I’m sorry if that’s harsh, but I’m pretty sure you know it’s true.”</p><p>“Okay, yes, sure, it’s true,” Lauren said.</p><p>Carson winced at her words as if they’d physically assaulted him. It wasn’t anger he felt, though. It was pain and a little bit of embarrassment. He’d let his wife down. He’d failed to meet her needs, which was really his only job as her husband.</p><p>“But cheating on Carson isn’t the answer,” Lauren said.</p><p>“Isn’t it, though?” Sophie replied. “What you did last night clearly fueled what happened this morning. You fooled around with someone and it unleashed the kind of passion that’s been lacking in your marriage. Carson responded to your desire and you two had great sex. All of that came from what you did last night.”</p><p>There was a pause before Lauren said, “Well, I can’t really argue with that, but it doesn’t seem like a long term solution. I feel really guilty about what I did last night and I don’t want to spend the rest of my life feeling that way. I really don’t, which means I can’t keep doing that. Eventually the guilt will kill me, or I’ll get caught and my marriage will blow up anyway, which I really don’t want.”</p><p>“I have a plan for that,” Sophie said.</p><p>“A plan?” Lauren asked. Carson was wondering the same thing. What sort of plan had his sister-in-law concocted?</p><p>“I think you’re underestimating your husband,” Sophie said.</p><p>“How so?” Lauren asked.</p><p>The call ended. Carson grabbed his phone and nearly dialed Sophie’s number. He couldn’t do that, though. Sophie had clearly ended the call. She’d cut him out of the loop right before sharing whatever plan she’d come up with.</p><p>Carson brought up his text with Sophie. He tapped the video of Lauren kissing in the booth. He watched another man finger her. He watched her kiss him. The arousal returned, and this time his cock grew stiff in his pants. He’d already experienced two orgasms using the video as fuel and his body was clearly ready for more. Carson put his phone down. As much as he wanted to masturbate, he wasn’t going to risk doing so at work. He resolved to finish his salad, clear his mind, and get through the rest of his day.</p><p>The smell of something delicious hit Carson’s nose as he stepped into the house. He dropped his bag and headed towards the kitchen.</p><p>“Hey honey,” Lauren said with a smile. “How was work?”</p><p>“It was good,” Carson replied. Apart from the distraction of listening to Sophie and Lauren talk, it had been a fairly standard day. “What smells so good?”</p><p>“I’m making fajitas,” she said. “Drinking those margaritas yesterday put me in the mood.”</p><p>“That sounds good,” Carson said.</p><p>“It will be. Sophie will be joining us for dinner, if that’s okay with you.”</p><p>“Of course,” Carson said.</p><p>Lauren smiled. “She’s out by the pool. I told her I’d bring her a Corona and totally forgot about it. Would you grab one from the fridge and bring it out to her?”</p><p>Carson opened the fridge, grabbed a bottle of Corona, and popped the top with a bottle opener. Lauren had a wedge of lime in her hand when he turned towards her and she gently placed it in the opening of the bottle and gave Carson a light smack on the ass as he headed out the back door.</p><p>“Your beer,” Carson said as he stepped outside, closed the door and approached Sophie, who looked relaxed and happy in a pair of shorts and a light sweater.</p><p>“Thanks,” she said. “Why don’t you sit with me for a moment?”</p><p>Carson sat, though he felt a little apprehensive given everything that had unfolded over the past two days.</p><p>“You watched the videos last night, didn’t you?” she asked.</p><p>Carson considered lying about it, but he couldn’t see the point in that, so he nodded.</p><p>Sophie pushed the lime into the beer and took a long sip. She smiled and asked, “You enjoyed yourself, didn’t you?”</p><p>“I don’t know,” Carson said. It felt like the honest answer. Watching the videos had turned him on, but he wasn’t sure if he actually enjoyed himself. The truth was, he’d run the emotional gamut while watching his wife kiss someone else.</p><p>Sophie rested the beer bottle between her legs and directed her steely gaze at Carson. “You understand that most men would have been angry or hurt or humiliated. Most men would have woken up their wives and gotten into a fight. Some men might have moved out on the spot and hired a divorce lawyer. Most men wouldn’t have fucked their wives the next morning. Most men wouldn’t have had a great orgasm fucking their wives the next morning.”</p><p>Carson looked away. He couldn’t hold Sophie’s gaze as he admitted, “Yes, I understand that.”</p><p>“Look at me,” she demanded.</p><p>Carson hesitated for a moment, but he looked back towards Sophie.</p><p>“You still have the videos on your phone, don’t you?” she asked.</p><p>He nodded.</p><p>“You get turned on when you watch them, don’t you?” she asked.</p><p>Carson didn’t answer.</p><p>“You don’t need to answer,” Sophie said. “I know the truth. I saw it in your eyes last night. I knew what kind of man you were the moment I showed you the first video. I know it wasn’t pure arousal. I know it was hard to watch, but I saw the desire in your eyes. I know some part of you liked seeing Lauren kiss someone else. I’ll bet you liked seeing him finger her even more. I’ll bet you would have watched him fuck her, too. That’s why you fucked her this morning. That’s why you made her feel good. That’s why you felt so good. It turns you on that she fooled around with someone else last night.”</p><p>“Sophie, please,” Carson said.</p><p>“You’re lucky I’m your sister-in-law,” she replied.</p><p>“Why?” Carson asked.</p><p>Sophie lifted the beer bottle to her lips, tilted it back, and took a long sip. “Because I’m going to make sure you both get what you want. I’m going to make sure your marriage is stronger than ever by the time I leave your guest house.”</p><p>She finished her beer and got up. Carson watched her walk away and step into the kitchen. He wondered if she was talking to Lauren about him. Were they discussing whatever they’d talked about after she’d hung up on Carson that afternoon? What did she mean by making sure that both Carson and Lauren got what they wanted?</p><p>Carson put his feet up and stared at the pool and the perfectly-manicured backyard Lauren had spent so much time crafting with the landscaper as all those questions rushed through his head. They were joined by one more: Why did he hope that Sophie’s plan involved Lauren fooling around with another man again?</p>
